A power management system for an electric vehicle is provided which maintains power to the various vehicle ‘always-on’ components and subsystems during periods of vehicle non-use without requiring the low voltage battery to undergo frequent charge/discharge cycling. The system uses a secondary DC/DC converter that has a lower output voltage, and operates at a higher efficiency, then the primary DC/DC converter. As a result of this system, the life of the low voltage battery is prolonged and power consumption efficiency is improved, thereby minimizing range loss while the car is parked.
